Luigi Auriemma discovered multiple buffer overflows in the
|
|
D_NetPlayerEvent() function, the Msg_Write() function and the
|
|
NetSv_ReadCommands() function. He also discovered errors when handling
|
|
chat messages that are not NULL-terminated (CVE-2007-4642) or contain a
|
|
short data length, triggering an integer underflow (CVE-2007-4643).
|
|
Furthermore a format string vulnerability was discovered in the
|
|
Cl_GetPackets() function when processing PSV_CONSOLE_TEXT messages
|
|
(CVE-2007-4644).

|
|
A remote attacker could exploit these vulnerabilities to execute
|
|
arbitrary code with the rights of the user running the Doomsday server
|
|
or cause a Denial of Service by sending specially crafted messages to
|
|
the server.

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
While some of these issues could be resolved in
|
|
"games-fps/doomsday-1.9.0-beta5.2", the format string vulnerability
|
|
(CVE-2007-4644) remains unfixed. We recommend that users unmerge
|
|
Doomsday:
|
|
</p>
|
|
<code>
|
|
# emerge --unmerge games-fps/doomsday</code>
|
|
</resolution>
